How Big Do Gulper Catfish Get? (Surprising Facts Revealed)

Have you ever heard of the Gulper Catfish? This unusual fish has a fascinating and mysterious appearance, with its large mouth and wide eyes.

But what is even more intriguing about this species is its size – just how big can these creatures get? In this article, we will uncover the surprising facts about the size of Gulper Catfish, and explore the unique features that make them so special.

So, if you’re ready to plunge into the depths of the mysterious Gulper Catfish, let’s get started!

How Big Do Gulper Catfish Get?

Gulper catfish, also known as the pelican eel, can grow quite large.

The average length of a fully grown adult is usually 2 to 4 feet, but some specimens can reach up to 6 feet in length.

They have a disproportionately large head and mouth, allowing them to consume prey much larger than their own body size – a trait that has earned them the nickname “pelican eel”.

These fish can reach up to 20 pounds or more in weight, due to the large amount of muscle and fat they contain.

Gulper catfish are not a common aquarium species, as they require a large tank to survive and a specialized diet of live prey, as they cannot consume prepared food.

It is best to leave them in the wild where they can thrive.

How Big Of A Tank Does A Gulper Catfish Need?

Gulper catfish are quite unique when it comes to tank size requirements, as they need more space than the average aquarium fish.

To keep them healthy and happy, you should provide them with an aquarium that is at least 80 gallons or larger, with a length of at least 5 feet.

The tank should also have plenty of rocks, driftwood, and a soft substrate such as sand.

If you have multiple gulper catfish, then you’ll need a much larger tank that is at least 150 gallons or more.

The depth and shape of the tank are also important considerations when it comes to keeping gulper catfish.

The ideal depth should be at least two feet and the tank should be more than five feet in length.

Shallow tanks should be avoided as the fish may not be able to reach the food at the bottom, while a tank that is too deep may prevent the fish from reaching the surface.

In addition to providing an adequate tank size and shape, gulper catfish need plenty of filtration to keep their water clean and free from toxins.

A good filter system is a must-have for these fish, as they are very sensitive to poor water quality.

Make sure that the water temperature is between 72 and 82 degrees Fahrenheit and the pH level is between 6.

5 and 8.


Overall, providing a comfortable, secure home for gulper catfish is key to their health and wellbeing.

Aim for a tank that is at least 80 gallons or larger, with plenty of rocks, driftwood, and a soft substrate.

This will give them plenty of space to move around and hunt for food.

Are Gulper Catfish Aggressive?

Gulper catfish are some of the most peculiar-looking fish in the world, with their unusual and distinct features.

But aside from their eye-catching appearance, they are also known for their behavior.

In particular, many people wonder if gulper catfish are aggressive.

The answer is both yes and no.

Gulper catfish have been known to attack other fish in the same tank, especially if they feel threatened or if there is not enough food to go around.

Nevertheless, they are generally peaceful fish and rarely attack unless provoked.

It is essential to provide plenty of hiding places in the tank for the gulper catfish.

This way, the fish will feel more secure and less likely to attack.

Additionally, it is necessary to feed the fish properly and make sure that there is enough food to go around so that the fish do not have to compete for resources.

Apart from providing plenty of hiding places and making sure the fish are well-fed, it is also significant to keep a watchful eye on the gulper catfish.

If they do start to become aggressive or threaten other fish, it is imperative to take action immediately.

This could include removing the aggressive fish from the tank or re-arranging the tank to create space between the fish.

In conclusion, gulper catfish are usually peaceful fish, but they can become aggressive if they feel threatened or if there is not enough food to go around.

By offering plenty of hiding places and making sure the fish are well-fed, it is possible to keep the fish in a peaceful and stable environment.

Nevertheless, it is essential to keep an eye on the fish and take action if they become aggressive.

Can Gulper Catfish Live With Other Fish?

Gulper catfish can be kept with other fish, provided certain conditions are met.

Generally peaceful and non-aggressive, they prefer to be housed with larger, non-aggressive species.

Keeping them with small fish, such as neon tetras, can cause them to become stressed and more aggressive.

As they are also sensitive to water quality, it is important to ensure that the tank is properly maintained and tested regularly.

When choosing tankmates for Gulper catfish, size and temperament should be taken into account.

They can grow up to 24 inches in length and can be quite aggressive, so it is best to avoid keeping them with small, peaceful fish.

Active species, such as tetras and barbs, should also be avoided.

The tank should also be large enough to accommodate the size of the Gulper catfish and its tankmates; a minimum tank size of 50 gallons for a single Gulper catfish, or 75 gallons for a group, is recommended.

In summary, Gulper catfish can be successfully kept with other fish, provided their tank is large enough and their tankmates are not too small or too active.

High water quality must also be maintained, and they should not be kept with small, peaceful species.

With the right conditions, Gulper catfish can make ideal tankmates for a variety of other fish.

How Long Does A Gulper Catfish Live?

The Gulper Catfish, a member of the Pimelodidae family, is known for its large mouth and long, slender body.

In the wild, the average lifespan of a Gulper Catfish is believed to be around 10-15 years, although this is relatively short compared to other species of catfish, which can live up to 20 years.

This may be due to the Gulper Catfish’s unique characteristics, such as its large mouth requiring more energy to move and maintain, or its solitary nature making it difficult to find a mate.

In captivity, however, the Gulper Catfish can live longer than in the wild.

Regular food, no predators, and experienced staff monitoring the fish’s health all contribute to a longer life expectancy.

With proper care, it is possible for a Gulper Catfish to live for a few extra years.

What Do Gulper Catfish Eat?

Gulper Catfish are a type of fish found in freshwater ecosystems around the world.

Their distinct shape and large, whiskered mouths are used to catch prey.

Gulper Catfish are opportunistic feeders, meaning they will eat whatever is available in their environment.

Their diet typically consists of small crustaceans, aquatic insects, worms, and other small fish, as well as plant matter such as algae, leaves, and other debris.

Gulper Catfish are bottom-dwellers and are mainly active at night, using their large, whiskered mouths to sense prey in the dark and create a suction to suck them in.

They are voracious eaters and can consume large quantities of food in a single feeding.

They prefer live prey but will also feed on dead animals if they come across them.

In captivity, Gulper Catfish should receive a balanced diet consisting of both protein and plant-based sources.

Prepared foods such as freeze-dried worms, bloodworms, shrimp, and other commercial fish foods can be provided, as well as live or frozen foods such as bloodworms, brine shrimp, and other small crustaceans.

It is important to provide an appropriate amount of food for their size.

How Long Do Gulper Catfish Live?

Gulper catfish (also known as the pelican eel) is a species of deep-sea fish that can be found in the Atlantic, Indian and Pacific oceans.

They have a unique look, due to their large mouth and extendable jaw which allows them to consume large prey items.

On average, they measure between 10-20 centimeters, making them incredibly small compared to other fish.

The exact life expectancy of a gulper catfish is still unknown.
